What does it use to prevent metal-to-metal contact in situations such as cold starts, where no fluid film is present? Do any of the other additives in oils "plate up" like moly? Reason I ask this is because of my continuing dilema...whether to run Pennz. Long-Life or not. Hmm...wonder why Delo does not have moly in its mix? ...I guess this is such a decision for me because my dad and I used Delo for years in his semis. I'm familiar with Delo, but the moly issue makes me think of becoming a Pennzoil guy. I realize I posted a question like this before, but I'm still looking for more info. By the way, if it helps any, this oil is going into a Chevy pickup with the 4.3L V-6.
